A token represents a logical chunk of a string. For
example, a typical tokenizer would break the string
"1.23 <= 12.3" into three tokens: the number
1.23, a less-than-or-equal symbol, and the number 12.3. A
token is a receptacle, and relies on a tokenizer to decide
precisely how to divide a string into tokens.
